In triangle abc it is given that AB =9 cm Bc=6cm and Ca = 7.5 cm also triangle def is given that ef =8 cm and triangle def similar to triangle abc then perimeter of triangle def is

Perimeter of ∆ABC = AB + BC + CA = 9 + 6 + 7.5 = 22.5 cm

∵ ∆DEF ~ ∆ABC

∵ PERIMETER ∆DEF BC

= ___

PERIMETER ∆ABC. EF

=> 22.5. 6

= __

Perimeter (ΔDEF) 8

perimeter of triangle Def = 22.5 x 8

= 30cm

6

the answer is 30 CM

answer: can and shows the work

step-by-step explanation:

domain is all the x values included in the

0 ≤ x ≤ 2

range is all the y values of the graph

-2 ≤ y ≤ 2

***keep in mind that there are different ways to show domain and range

hope this !
